Actuators in the Subsea industry

Olsen Actuators & Drives have a wealth of expertise in supplying Electric Roller Screw Actuators, rugged Motor Drives, and electro-mechanical solutions to the Subsea sector.

Actuators are the component in a mechanical system that provide linear or rotary movement. In the Subsea Industry, the harsh environments can be severe with pressure, corrosion and temperature challenges. Olsen understands our actuators need to be dynamic, robust, reliable, fast responding and prevent the ingress of sea water and other contaminants. Im many cases the actuators are required to be very powerful to replace legacy hydraulic fluid power systems.

Olsen provide solutions for a variety of applications such as subsea wellhead valves, subsea chemical injections valves, subsea hatch controls, and ROV controls and robotic arms and controls. We also specialise in designing test rigs and process control on subsea equipment from subsea manifolds and structures, ROVs and submarines.

Our subsea actuators, are extremely durable, and provide high accuracy and repeatability, with extended life expectancy, that reduces maintenance that is costly and time-consuming in subsea environments.

Designed and tailored in the UK and shipped globally, our actuator solutions can incorporate integrated drive electronics, requiring no pipes or cooling and are incredibly lightweight and compact in comparison with hydraulic or pneumatic systems. Electrical roller screw actuators deliver a highly accurate level of force and position control (with condition monitoring 4.0) to solve some of the most challenging applications.

The longevity and low maintenance offered through our unique roller screw technology are particularly popular where product failure or downtime can be critical and very costly. A simple to use Windows based interface means the actuators are quick to install, and commission and simple to maintain.

The efficiency benefits are also significant. Removing the need for messy, leaky and corrosive hydraulic fluids, and with significant operational energy, weight and space savings, Olsen actuators are providing key solutions in an increasingly efficiency driven market, while reducing environmental pollution and spills.

Olsen Actuators & Drives are an industry leader in roller screw electro-mechanical control systems. We love to explore new applications, requirements and restrictions that create the development of new solutions that drive the industry forward. If you have any questions regarding an existing or new project, we would be delighted to discuss them with you.
